On Social-technical Control of Safety Development in Economic Transition Background

Xue-qiu He,Song Li

Frontiers of Engineering Management 2015, Volume 2, Issue 3,   Pages 234-240 doi: 10.15302/J-FEM-2015025

Abstract: Industrial safety and economic growth, two vital and inextricable forces affecting national culture and development, are worthy of much more interest and attention than this article can hope to generate. Following economic growth, industrial safety remains as a high priority in this nation’s quest for sustainable development. At present, while China is on its way to transforming its economic structure and growth models, talk of industrial safety appears with special regularity, for it also is undergoing profound changes as an important facet of modern China.
